The For considerable period of time the Calvin cycle as described earlier was thought to be the only photosynthetic reaction sequence operating in higher plants and algae.

It is most commonly used by plants; While plants in tropical area, convert the sunlight energy into C4 carbon molecule or oxaloacetic acid, this cycle takes place before the C3 cycle and then with the help of enzymes it carries the further process of getting nutrients, is called C4 plants and pathway is called as C4 pathway. C 4-cycle occurs in 1500 sps. During photosynthesis, the light reaction is followed by the dark reaction. ADVERTISEMENTS: In this article, we will discuss about the C4 – Dicarboxylic Acid Pathway (Hatch–Slack Pathway). With the result, a C 4 acid, oxaloacetic acid (OAA) is formed.

The C4 cycle involves two carboxylation reaction, one taking place in chloroplasts of mesophyll cells and another in chloroplast of bundle sheath cells. vin cycle. C4 (Hatch and Slack) cycle 1. in C 3 mode of photosynthesis requires 2NADPH + 3ATP molecules while in C 4 mode of photosynthesis 2NADPH + 5ATP molecules are required (additional 2 ATPs are needed in reaction no. First stable product of this reaction is OAA., which is 4C, DCA (Dicarboxylic Acid), thus Hatch & Slack pathway is called as C 4 cycle or DCA . %PDF-1.5 The C 4 photosynthetic carbon cycle is an elaborated addition to the C 3 photosynthetic pathway. C4 plants have evolved mechanisms to improve photosynthetic efficiency and decrease water loss in hot, dry environments, and also to reduce stomatal conductance and conserve water without diminishing rate of carbon fixation. Plant such as maize, sugarcane, Amaranthus & numerous tropical grasses undergo C4 cycle for fixation of CO2. The first stable product is a 4-Carbon compound, oxalo acetic acid (OAA). Two CO2 fixation. Start reaConverter and load all the .c4 files you intend to convert into .pdf because, as opposed to most free online converters, reaConverter supports batch conversion.
